Volume computation: earthworks, stockpiles and basins

When is it needed

• Earthworks interim statements on a site.
• Stockpile inventory.
• Capacity of a basin or a reservoir.
• Fill of a platform.

Our work

1. Initial survey. Natural ground or reference state.
2. Successive surveys. On the ground or by drone depending on the area.
3. Computation. DTM (digital terrain model) difference and cross-sections: two methods that check each other.

Examples of assignments

• Monthly earthworks statements
• Aggregate stockpile
• Irrigation basin
• Industrial platform

What you receive

• Initial and final topographic plans
• Cross-sections
• Volume summary sheet

Reference framework

• ONIGT (National Order of Surveying Engineers) Standard 03
• ONIGT Standard 12 (volume computation)

Where we work

Based in Casablanca (Aïn Sebaâ), the firm carries out this service throughout Morocco: Greater Casablanca, Rabat-Salé-Témara, Fès, Tangier, Agadir, the Oriental and the South. Its survey crews travel to the site for the duration of the assignment.
